The removal of methylene blue dye from waste water using Jumbo grass (Sorghum Bicolour Sorghum Sudanefe) has been studied experimentally by batch mode methods. The newly prepared bio-adsorbent was characterized and the adsorption capacity of the bio-sorbent was investigated by changing the parameters such as adsorbent dose, pH, contact time and initial dye concentrations. From the experimental data the Langmuir, Freundlich and Temkin adsorption isotherm models were arrived and the Pseudo second order, Elovich and Intra-particle diffusion kinetic models were also analyzed. Equilibrium data were well fitted to the Langmuir isotherm, Freundlich and Temkin model. Adsorption process was obeyed the Pseudo second order and Elovich kinetic models. The Langmuir adsorption capacity of adsorbent was found to be 12.99 mg/g. The results reveal that the raw Jumbo grass serves as low cost adsorbent for removal of methylene blue dye from waste water.
